I use this as a home jewelry box - I don't wear a lot of jewelry, so it fits my needs perfectly. Its pretty lightweight and would be good for travels as well. The outside is leather-like and seems to be waterproof so far. I use the first layer for jewelery and second layer to store my hairclips and pins. I've had it for a few months and it seems to be great quality and durable! Definitely a good value as well because I've seen similar jewelry boxes sold at popular retail stores for over $30.

Lovely Slate Gray Jewelry Box

I just received this Slate Gray jewelry box. It's really quite lovely and just the right size for my granddaughter's vanity. I'm really excited about giving it to her, for her 12th Birthday, to hold her better jewelry. It's so nice I'm going to order another one for my other Granddaughter's Birthday.
